At the beginning of each play session, roll 1d. On 1-3, you are in your manic phase; 4-6 indicates depression. Every five hours of game time thereafter, roll 3d. A 10 or less indicates that you begin a mood swing. Over the next hour, you shift from your current phase to the opposite one. You remain in the new phase for at least five hours, after which you must again roll 3d.
